SHUTTLE-BINDER FOR LOOMS.

Specification of Letters Patent.

' Application filed June 13, 1913. Serial No. 773,432.

Be it known that I, Non LARIVIERE, a citizen of the United States, residing at Baltic, in the county of New London and State of Connecticut, have invented a certain new and useful Improvement in Shuttle-Binders for Looms, of which the following is a speci -This invention. relates to the mechanism commonly provided in looms of the reciprocating batten type for'checking and clamping the filling shuttle as it is thrown from end to end of said batten by the picker stick, and my present purpose is to provide novel and eifect-ive clamping mechanism by means of which the power required for throwing this desirable end in view I have provided the clamping device illustrated in the annexed drawings, in which Figurel is an end elevation of a loom batten and those, parts connected therewith which relate particularly to my present im provement. ig. 2 is a front sideview of the same parts, and. Fig. 3 is a relatively enlarged, plan view of one of the shuttle, boxes, showing also the special form of finger proyided by me for cooperating with said box to clamp the shuttle in its inactive position.

Referring to these drawings, the numeral 10 indicates the batten, or so called lathe, of a loom, said batten being attached to, and

carried by, the upper (free) end portions of so called swords 11 that'are suitably hinged at their lower -ends. Thesaid batten is connected, by means of an arm 12, with a crank 14 carried by'a shaft 15 which latter is journaled in the loom frame and is driven in the usual, or in any other suitable, manner; each revolution of said shaft causing the batten to swing forward and backward a prescribed distance in order to, first, permit the shuttle to be thrown along the batten between the separated warp threads and then to lay up the filling thread.

The numerals 16 indicate as a whole, shuttle boxes located atthe opposite ends of the batten and adapted to receive the shuttle as it is forcibly thrown along said batten The mechanism most commonly provided by this type of looms for receiving and checking the shuttle consists of a box having one rigid side wall and an opposing spring controlled yielding side I wall: the shuttle being thrown with such force that it crowds its way in between the two described walls until it is stopped by the friction resulting from the sliding im-- pact of the shuttle with side walls of the shuttle box. p

In my present, improved, form of shuttle Patented May 26, 1914.

binder I provide a shuttle box, at each end of the batten, consisting of a rigid side 16 and an opposed yielding, side 16 which latter, as here shown, is hinged at 17. This yielding side 16 is controlled as to its position by a finger 18 that issecured-to a suitable rock-shaft 19 that is journaled in bearings 20 secured to the batten 10 and, by

preference I utilize for such shaft the socalled protection rod which is usually embodied in this type of looms. said shaft 19 is an arm 21 andhinged to the sword 11 is a similar 'arm 22 whose free end is connected, by means of'a rod 23 with an angle armor plate 24 thatis adjust-ably pivoted to the crank arm 12 already men- Secured to I tioned. The free end of arm 21 has hinged I thereon a rod 25 which extends downwardly, through the arm 22, and said rod has mounted on its lower end portion a spring 26, one of whose ends abuts the lower edge of said arm 22 and whose other end abuts a nut or collar 27 secured to thesaid rod, as is best into said shuttle box. Meanwhile the spring. 2

26 permits the finger 18 and the hinged side 16 to yield slightly as the shuttle enters the box. Just at the instant when the picker stick is about to strike the shuttle to throw the latter out of the box and to the other end of the batten, the crank arm 12 and 'rod 23 raise the free end of arm 22, and the finger 18 is moved outwardly sutficiently to free the hinged side 16 of the shuttle box and thus permit the shuttle to leave the box without the frictional hindrance common to the spring-controlled boxes now in almost universal use. At each revolution of the crankshaft yielding pressure is thus applied to the hinged box side 16 by the finger 18, resulting in gradually checking the shuttle as the lever and said actuatinomember a drivin H 9 5 member and independent connections between said driving member and the batten and said driving member and said lever for imparting bodily movement to the batten and movement to the said movable wall in timed relation to the movement of the batten said independent connection for imparting movement to said wall comprising an adjustable angle plate and a link.

2. In a device of the character described, the combination with the swords of a loom, of a batten supported upon said swords, a

shuttle box carried by said batten and comprising a movable side wall, an actuating member for said movable wall pivoted upon said batten, a lever pivoted upon one of said swords, a rod pivotally connected to the actuating member and passing through said lever, a collar carried by said rod and a spring bearingbetween said collar and said lever.
